COMPOSITION FOR PRESERVINGjPILES AND TIMBER.`

To all whom it may concern: l

Be it known that I, PETER S. SMoUT, a citizen yof the United States, residing at Everett, in the county ofSnohomish and State of Washington, have invented a Composition for Preserving Piles and Timber, as hereinafter set forth.

The accompanying drawing represents in perspective a portion of a pile withmy improved composition applied.

My invention relates to that class of pileprotectors which consists of a suitable composition of matter applied to the exterior of the pile and forming a covering therefor which is intended lto resist not only the action of the water, but the ravages of marine insects, particularly the teredo. l

My invention consists of two coverings for the piles, as follows:

' First. Of an inner coating which is composed of the following ingredients, combined in substantially the proportion stated, to wit: rosin, five pounds; tallow, one` pound. The manner 'of mixing these is as follows: The tallow is put in a kettle and raised to a boilingpoint. The rosin is then put into the kettle and well stirred in and beaten with-the tallow until the mass becomes of a waxenor creamy consistency. The proportion of rosin need not be exactly as above given, so much being used as will give the proper hardness to the mass when set andvarying according to the average climatic temperature where used. The mixture is then applied with a brush, swab, or other implement to the pile or timlber to be treated. v

Second. l The second covering consists ofthe following ingredients in substantially the. proportion stated, to wit.: tallow, one pound; rosin, ten pounds, and ten pounds of brimstone. yThe manner of mixing these is as follows: The tallow is put in a kettle andraised to a boiling-point, and the rosinis then added, thoroughly stirred and beaten until the whole reaches a thick waxy consistency. 1 While the solution is kept at the vboiling-point the brimstone is added and thoroughly stirred in and `mixed with the other ingredients until it is dissolved, when a quantity of hair or other suitable liber is added and thoroughly mixed Awith the plastic mass.

hair may be one-half pound, the solution being allowed to cool to such a degree before the hair or ber is added that the latter will not be destroyed. The second coating is aptwine thoroughly saturated with the solution.

composing the first coat or covering above described, and a coating of the second composition is applied over the rope. The whole is then protected by strips of copper Wire placed at .frequent intervals and running lengthwise with the pile, the same being securely fastened by copperstaples driven into the pile. The first coating adheres to the wood and slightly penetrates its surface. The second coating forms'a hard mass and with the sand and fiber renders the Wood water-tight and air-tight, and the sand and hair or fiber prevent any marine insects from penetrating thel coating, while the brimstone causes the 4entire mass to become hard and dense, so that it is impermeable to air and salt water. The lrope and copper wire prevent the covering frorninjury by contact with vessels or lioating matter on the water. The rope or cord composed of bers cannot be penetrated by the teredo or other marine insects, and, further, the rope being bound about the pile and its .ber running at right angles to the ber of the pile the teredo cannot get access to and penetrate or bbre the wood.

` What I claim as new is- A pile-protecting composition consisting of tallow, rosin, brimstone, hair, and sand, as
